Marco Casario has been passionate about informatics since he was little more than a child and used to program games in Basic for Commodore 64 before dedicating himself to innovative projects for the web using Flash and HTML (as far back as versions 2). In 2005, Marco founded Comtaste, a company dedicated to exploring new frontiers in Rich Internet Applications and the convergence between the web and the world of mobile devices -- MobyMobile and YouThru are representative of their recent work.

He is founder of the HTML5 italian community, HTML% Italy (http://www.meetup.com/HTML5-Italy/), the biggest worldwide Flash Lite User Group and of AUG Italy, a reference point for the Italian community of Adobe users, in which he carries out the role of Channel Manager for the section dedicated to Flex (AUG Italy Flex Gala).

He is author of the following book project:
Flex 4 Cookbook (O'Reilly)
Professional Flash Catalyst
AIR Cookbook (O'Reilly)
Advanced AIR Applications (FriendsOfED)
The Essential Guide to AIR with Flash CS4
Flex Solutions: Essential Tecniques for Flex 3 developers (FOED)
Other co-author and technical editor's jobs are:
Professional Flex 2
Essential Flash 8
Flash Application for mobile devices

"When it comes to doing real hands-on work with Flex 4, this is definitely a great reference book. However, its concentration on Spark and relatively light coverage of MX components makes it a complementary volume to The Flex 3 Cookbook rather than a replacement of it. For the foreseeable future, serious Flex developers may want to keep both editions within arm's reach."
